When I was competing in the 1980's this was common practice. Studio owners used competitions as a way to encourage their students to sign on for large blocks of prepaid lessons. By "fixing" competition results, those unsuspecting students were enticed to spend and spend and spend. This may not be the current practice everywhere, but I wouldn't be surprised if it did rear its "ugly head".

I would encourage you to continue to question these practices whenever you encounter them, join USABDA and try their competitions as I did not experience this kind of preferential judging in that arena.

Finally, be aware that some partnerships have a reputation in the ballroom dance community. They do tend to place higher, however, there place has been earned through experience. When you gain experience you too will find your position at competitions improve and if not, get a new coach. It is possible to stay with one teacher too long.

I wish you well in your ballroom dancing. Demand honesty! it is your right!
